If the last two years of crisis in investing in Chinese companies proves anything, it’s that any Chinese company that pays more tax than it should, documents every transaction and practices the most forensic accounting methods is the one with the calmest, happiest investors. Such companies are very rare among the thousands invested in by private equity, and not very common among publicly-traded ones, if securities regulators in the US and Hong Kong are to be believed.

Chinese companies, especially private ones, live under a cloud of suspicion their books are cooked, while their auditors turn a complicit blind eye. While that cloud hovers, it will remain impossible for Chinese private companies in large numbers to successfully sell their shares to the public through an IPO. Chinese companies already listed are not much better off. For many, their share prices remain seriously depressed because of investor doubts about the accuracy of the financial accounts.
